+# README for Docker Image Build and Publish Workflows
+
+## Overview
+
+This repository contains two GitHub Actions workflows that automate the building and publishing of Docker images to an OCI registry. 
+
+### Workflows
+
+1. **On Commit to Main**
+   - **Trigger:** Activates on commits to the `main` branch (tags are excluded).
+   - **Purpose:** Builds and publishes a Docker image for each commit.
+
+2. **On Tag Push**
+   - **Trigger:** Activates when a new tag is pushed.
+   - **Purpose:** Builds and publishes a Docker image for the tag and tags it as `latest`.
+
+## Prerequisites
+
+- **Secrets Needed:**
+  - `OCI_TOKEN`: Your OCI registry token.
+  - `OCI_USER`: Your OCI registry username.
+
+## How to Use
+
+1. **Clone the Repository:** Get a local copy of this repository.
+2. **Modify Dockerfile:** Update the `Dockerfile` for your application.
+3. **Push Changes:** Push changes to the `main` branch or create a new tag.
+4. **Check Workflow Status:** View the Actions tab in Forgjo to monitor workflow runs.
+
+## Notes
+
+- Ensure your Docker environment is compatible with multi-platform builds if necessary.
